Title: Improvements in or relating to mirrors for taking kinematographic pictures
IPC: G03B15/08
Filed: 1924-02-25
Abstract: 233,645. Withers, J. S., (Akt.-Ges. f³r Spiegeltechnik). Feb. 25, 1924. Reflectors.-Kinematograph pictures are produced by erecting only a portion of the object in its natural size, this portion being reproduced by a mirror 7 having a contour which corresponds with part of the object on a reduced scale, the remainder of the scenery 9 being arranged at the rear of the mirror, either actually or as a picture so that when combined with the image shown by the mirror, the complete object is reproduced. The mirror 7 consists of a number of sections 11 arranged in any desired manner between glass plates 13, 17 in accordance with the outline of the objects to be reproduced and may be dovetailed together, being held in position by clamping screws 16. The non-reflecting portions of the mirror 7 mav be made of transparent sections similar to the reflecting sections 11, and in one modification arrangements are made for a complete mirror surface covering the whole of the field of view to cover the sectional mirror 7 so that when the actors are not completely reflected in the sectional mirror 7 by reason of its limited contour, the complete mirror surface is used, and the photographs taken in these circumstances are utilized to form with photographs taken without the actors in position composite photographs of the scene. The joints of the sections 11 are covered by reflecting strips on the back of the front glass plate 17.

The screening deck of the parent Specification is supported by means which permit the deck to be bodily displaced but to which the deck is connected so that it can be swung about one or more predetermined axes from one position into another in which the deck has the same spatial location but is reversed end for end. In Fig. 2 a curved screen 20 is displaced bodily in a direction A from its position on a fixed box 22 by movement of a yoke 27 and rod 29 suspended from a carriage 30 travelling along a track 31. The screen is then swung about trunnions 26 until a stop 28<SP>1</SP> engages the yoke, and is thereafter rotated through 180 degrees about the rod 29 and traversed back to the box 22. In Fig. 4 a screening deck 40 is displaced from a box 42 in a direction towards its centre of curvature by a column 44 to which the deck is secured. The column is then rotated through 180 degrees and thereafter retracted. The displacing may be performed hydraulically or pneumatically. In Fig. 5 a screening deck 60 together with a box 61 having openings 62 for liquid and undersize is moved bodily along a surface 65 by means of a wheeled carriage 64 away from a following screen 70 and hopper 67.

Patent GB-349685-A (GB)
Title: The manufacture of new organo mercury compounds and of preparations comprising the same
IPC: C07F3/12
Filed: 1930-03-18
Abstract: Organo mercury compounds are prepared by treating 3-nitro-4-hydroxytoluene with a mercuric compound, boiling the product with aqueous alkali and evaporating the filtered solution in vacuo in the absence of carbon dioxide.  When mercuric acetate is employed as the mercuric compound, acetoxymercuri-3-nitro-4-hydroxytoluene is obtained as intermediate product and chloromercuri-3-nitro-4-hydroxytoluene when mercuric chloride is used.  These intermediate products are insoluble in water but are rendered soluble by the subsequent boiling with alkali, which converts them into the alkali metal salts of hydroxymercuri-3-nitro-4-hydroxy-toluene.  Solutions of these salts, which possess germicidal and antiseptic properties, readily absorb carbon dioxide from the air with formation of a precipitate, but the deposition is delayed by the addition of a little alkali or of a buffer salt, e.g. by solution in a 1 per cent aqueous solution of trisodium phosphate.ALSO:Solutions of the alkali metal salts of hydroxymercuri-3-nitro-4-hydroxytoluene, useful as germicides or antiseptics, are stabilized by addition of a little alkali or of a buffer salt.  An example is given of the solution of the sodium salt of the above mercury compound in a 1 per cent aqueous solution of trisodium phosphate.

Abstract: 679,347. Projectiles. SCHLUMBERGER OVERSEAS SOC. ANON. April 16, 1951. No. 8836/51. Class 9 (i). Projectile for a gun-perforator for use in well casings comprises a casing-piercing member 10 having a pointed nose 12 and a sub-calibre cylindrical portion 11 surrounded by a sleeve 13 of the same diameter as the bore of the gun. The sleeve has a shoulder 14 bearing against the base of the projectile and is made of hard, brittle metal, such that it flattens out burrs made in the casing by the projectile and is disintegrated by the impact. The metal may be cast iron or brittle steels. Weakening grooves 15 may be formed in the sleeve. Mounted on the member 10 in front of the sleeve is a stopper member 16 of flexible material, e.g. rubber. The stopper member has a flange 17 which is forced by the pressure of the well fluid into engagement with the wall of the gun bore 18. Behind the projectile is a powder charge 21 ignited by known means to fire the projectile. In a modification, the stopper member is not flanged but is surrounded at the rear by a soft metal ring 22, e.g. annealed copper, having an inwardly extending flange 23. The purpose of the ring is to prevent the stopper member flowing around the burr elimination member 13 due to hydrostatic pressure.

Abstract: 804,906. Analogue calculators. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 8, 1952 [April 18, 1951], No. 9107/51. Class 37. An inductive potentiometer, for evaluating the rate of change of a variable, comprises an array of sections, switches between adjacent sections operable in cyclic order and means for feeding an electrical signal to a fixed point in each section. As shown, the potentiometer is formed by the inductances L1 to L10 connected by the switches A1 to A10. Alternating current voltage analogues of the observed values of the variable are fed to the stores S1 to S10 and the switches are opened and closed cyclically. The voltages at S1 to S10 have a space distribution along L1 to L10 which corresponds with the time distribution of the observed values. The voltage distribution along L1 to L10 is linear, due to the tightness of the coupling between the sections and the voltage at the secondary winding L is representative of the mean ratio of change of the observed variable. Specifications 740,071, 802,799, [Group XXXVIII], and 804,905 are referred to.
